The problem can be resolved as follows
问题可以如下解决
- By using the
react nativecommand line $ react-native bundle --entry-file ./index.ios.js --platform ios --bundle-output ios/main.jsbundleusing this in the root of the react native project- When the
main.jsbundlefile is generated add it back to theAdd Files to Projectoption - Just verify that the file is included in the build phaseand
re-build
- 通过使用
react native命令行 $ react-native bundle --entry-file ./index.ios.js --platform ios --bundle-output ios/main.jsbundle在本机项目的根目录中使用它- 当
main.jsbundle文件生成其重新添加到该Add Files to Project选项 - 只需验证该文件是否包含在构建阶段，然后
re-build

i am using react-native version- 0.47.1in my case after running the command suggested by @pritishvaidyasolved the main.js bundle issue, but even in release build i could see the yellow warning boxes. So i modified the command by adding --dev false. That did the trick. Leaving this updated command here in case, someone is stuck like me.
在运行@pritishvaidya建议的命令后，我正在使用react-native 版本 - 0.47.1解决了 main.js 包问题，但即使在发布版本中，我也可以看到黄色警告框。所以我通过添加--dev false修改了命令。这就是诀窍。把这个更新的命令留在这里以防万一有人像我一样卡住了。
react-native bundle --entry-file ./index.ios.js --platform ios --dev false --bundle-output ios/main.jsbundle --assets-dest ./ios

If you're ejecting from create-react-native-appon react-native v0.50+ the index.ios.jsand index.android.jsfiles are now combined into index.js
如果您从create-react-native-appreact-native v0.50+ 中弹出，则index.ios.js和index.android.js文件现在合并为index.js
Before or after ejecting run
在弹出运行之前或之后
npm i -g react-native-cliif you npm install
npm i -g react-native-cli如果你 npm install
or
或者
yarn global add react-native-cliif you yarn install
yarn global add react-native-cli如果你 yarn install
...After Ejecting...
...弹出后...
[bad advice]run react-native bundle --entry-file ./index.js --platform ios --bundle-output ios/main.jsbundle. <-- Do Not do this.
[不好的建议]运行react-native bundle --entry-file ./index.js --platform ios --bundle-output ios/main.jsbundle。<-- 不要这样做。
[UPDATE] The main.jsbundle is created when xcode opens the terminal bundler. make sure you don't close the terminal window and it will run fine.
[更新] main.jsbundle 在 xcode 打开终端打包器时创建。确保您没有关闭终端窗口，它会运行良好。

I'm on a mac. I'm new to react native, I had the same issue. After 2 hours of trying everything suggested, I solved it. I realised that you need to first start it on a different tab inside the terminal and then run the command "react-native run-ios". So if you still have problems, open terminal, have 2 tabs open.
1) First cd to your project and enter "npm run start".
2) Then go the second tab and enter "react-native run-ios". That should do it.
我在 mac 上。我是本机反应的新手，我遇到了同样的问题。在尝试了所有建议的 2 小时后，我解决了它。我意识到您需要首先在终端内的不同选项卡上启动它，然后运行命令"react-native run-ios"。因此，如果您仍有问题，请打开终端，打开 2 个选项卡。1) 首先 cd 到您的项目并输入"npm run start". 2）然后转到第二个选项卡并输入"react-native run-ios"。那应该这样做。
If you have problems with "react-native run-android"then you should have its simulator open beforehand. Open a third tab and go to ~/Library/Android/sdk/tools, then enter "./emulator -list-avds"to see your installed android simulators, then start one with "./emulator -avd {your-emulator-name}". When you are done, hit "react-native run-android".
如果你有问题，"react-native run-android"那么你应该事先打开它的模拟器。打开第三个选项卡并转到~/Library/Android/sdk/tools，然后输入 "./emulator -list-avds"以查看已安装的 android 模拟器，然后以"./emulator -avd {your-emulator-name}". 完成后，点击"react-native run-android"。
